Full Description

The objective of this study was to provide sufficient information to specify and build a cost effective treatment process to meet the proposed new European standard of 10 ug/L for arsenic in potable water. Laboratory scale tests were undertaken to assess the relative efficiencies of a number of treatment options. These eliminated granular activated carbon (GAC) and flocculation as possible treatment processes. Subsequent pilot-scale trials were then carried out to determine the adsorption characteristics of arsenic with several different media including activated alumina of various mesh sizes, activated bauxite, granular ferric hydroxide, ion exchange resin and catalytic manganese dioxide. This paper concentrates on activated alumina which was demonstrated to be the most viable media.
